To an whom it may concern:

Be it known that l, donrn Howann WAY, a citizen of the United States, residing in the city and county of Philadelphia and State of Pennsylvania; have invented certain new and useful lmprovements in Hinges, whereof the following is a specification, relerence being had to the accompanying drawings.

The invention relates to hinges such as are ordinarily employed in the mounting of doors, shutters, sashes, or other similar building appurtenances.

The invention is more especially directed to means for preventing independent rota-- tion oil the hinge pintle, and is applicable either in ordinary leaii hinges, or in adjust able hinges in which the pintle is formed. with relatively concentric and eccentric sections, such as shown and described in the United States Patent l lo. l,208,t22, granted me, under date oil December 12, 1916. lln.

" the former instance, the improvement is ad vantageous in preventing the pintle from working out, due to induced. independent rotation, and in the latter instance, to llX the pintle'in adjusted positions.

'lheinvention is further directed to a socket member for sustaining the end of the till till

pintle, said member being provided with simple means functional in rigidly retainin the same in one of the hinge knuckles, an so constructed as to facilitate ready assembling initially.

, 'llhe organization characteristic of my in vention involving the advantages above pointed out, will be best understood from the detailed description which follows:

ln the drawings, lfiigure l, is a "lace view of a hinge conveniently embodying my in vention, the interfitting pivot knuckles bem shown in section.

ig. ll, is a cross section through the hinge, as viewed in the direction of the arrows lit-ll, in Fig. l.

l i. lll, is an elevation of the socket memer'within which the end of the pivot pintle is sustained, and

Fig. llll, is a modified form of my inven tion.

In its general aspect, the hinge which l have herein illustrated is similar to the structure set lorth in the patent above re ferred to. ln this instance, the hinge leaves are represented at 1, and a, the former being provided with the pivot knuckles 2, 3, and the latter with the inter-fitting knuckles 5,6, '3". 'llhe cooperative pivot pintle comprises the concentric sections 8 and 9,-and an intermediate eccentric section. 10. The

sections 8 and 9, are respectively sustained in the'knuckles 5 and 7, of the leaf it, while the knuckles 2 and 3, of-the plate swing about the eccentric section 10, of the pintle.

lln order tolacilitate the rotative adjustment of the pintle, it is supplemented at its upper end with a head 11, slotted at 12, so as to be engageable by a screw driver, or other suitable implement available for the purpose. lby this construction, it will be readily seen that the pivotal axis of the hinge may be adjusted so as to compensate for any inaccuracies in initial mounting oi, a door or any binding that may subsequently occur through warping or shrinkage.

For the purpose oi. preventing rotation oil the pintle alter the desired adjustment has been obtained, the same has been provided with an enlargement 13, having the polygo nal cross sectional configuration clearly shown in llig. ll. This enlargement 13, is prelerably formed integrally with. the pintle, directly beneath its head 11, and adapted to engage within a correspondingly shaped socket formed in the outer knuckle 5, ol the leaf 4.

While the enlargement 13, and its socket may have any appropriate configuration, the octagonal form shown serves the purpose satisfactorily in practice. it will be noted lrom liig. ll, that the sides of the polygon are somewhat concaved so as to allord, by reason oil the sharper corners thus formed, a firmer interlock than would be possible by a straight sided configuration.

'llhe anti turning feature above described, while it is more particularly necessary in an adjustable hinge, such as herein illus trated, may however be incorporated to advantage in an ordinaryhinge to prevent the pintle from shitting longitudinally in the hinge knuckles, as often happens through induced independent rotation.

its will be observed t'rom Fig. l, the lower reduced end 9, of the pintle is sustained within an opening 15, formed in a socket member 16. @aid member has a substantiall cylindrical inner extremity 17, lll which is received in the hinge knuckle 7 and formed with a peripheral projection 18, which co-acts with a correspondingly shaped internal groove within the knuckle, in preventing displacement. it will be till llti

ltlll lid noted that the projection 18, is tapered, so,'

. to the socket member. Said member is preferably provided with a spherical head 19, which serves as an ornamental counterpart of the pintle head 11.

Fig. IV, shows a modified form of my invention as applied to a Fbutt hinge where in the knuckle 20, is integrally cast or forged with the leaf 21. In this instance, the equivalent of the socket, hereinbefore described, is in the form of a recess 22, having parallel 'sides prolonged in one direction to the edge of the knuckle. These parallel sldes cooperate with opposite faces of the polygonal portion of the hinge pintle, the latter bein represented in dotted lines at 23, in the gure. The socket parallel sides prolonged to the'edge of the knuckle as thus described, is entirely effective, and much more easily formed especially in a cast leaf.

Having thus described my invention, I

claim:

In a hinge, the combination of a pair of leaves formed with interfitting' pivot knuckles; a cooperative pintle provided at one end with a head; a socketed member for sustaining the opposite end of the pintle, said member being provided with a peripheral shoulder serviceable as a retainer in cooperation with an internal groove in one of the hinge knuckles, and formed with a tapering approach functional, during assembling, in expanding the knuckle until the shoulder finds its seat within the groove.

In witness whereof, I have hereunto signed my name at Philadelphia, Pennsyl- Vania, this 2nd day of May, 1919.
